Answer:
the Hight of kite is =12×sin45
therefore,8.5 feet
Answer:
Option D.
Step-by-step explanation:
If two triangles ΔABC and ΔA'B'C' are similar then we take point C of ΔABC to find the transformation performed form C to C'.
Coordinates of C are (0, 3) and the coordinates of C' are (0, -1).
This shows that C is rotated 180° about origin to get the new coordinates as (0, -3) and then new coordinates were dilated by 1/3 which forms C' as (0, -1)
Therefore option D is the correct option.
The missing number is 20
<h3>How to determine the number</h3>
We can see that the values at the top must be made equal to that at the bottom
For the top, we have
30 + 11 = 41
For the bottom, we should have:
21 + x = 41
Now, let's solve for 'x' to determine the missing figure;
21 + x = 41
collect like terms
x = 41 - 21
x = 20
Thus, the missing number is 20

It’s definitely-20
Add 9 to both sides to cancel it out so it is now
4x-20=5x
Than subtract 4x on both sides it is now
-20=x
Because 5-4 equals 1 and 1x is just written as x
